This report summarizes wind tunnel experimental measurementson the aerodynamic interaction between members of misaligned platoons. Experiments are conducted at the University of Southern California's Dryden Wind Tunnel Facility. All experiments are made using 1/8 scale models of 1991 Chevy...

The present study aims to document the drag reduction for a two-vehicle platoon by operating two full-scale Ford Windstar vans in tandem on a desert lakebed. Drag forces are measured with the aid of a special tow bar force measuring system designed and manufactured at USC. The testing procedure...

The project reuses the sensor and actuator interface software developed by California PATH for the DEN1097 automated highway system demonstration on Highway I17 in San Diego during August 1997. This software is provided on the QNX operating system. It interfaces with the magnetometers, radars,...

Keywords longitudinal control, car platooning, back-stepping control, multi-surface dynamic sliding mode control, integral filters, realtime control code This report presents the development of nonlinear longitudinal controllers and their realtime implementation for Automated Highway Systems...

The objectives of the project are: (1) to study the behavior of existing vehicle lateral control systems in the event of magnetometer failures, (2) to design controllers that use the output from only one set of magnetometers, and (3) to develop an autonomous lateral control scheme that uses no...

This report describes the results of an effort to implement and analyze the performance a vehicle control system using control state information obtained from a carrier phase Differential Global Positioning System (DGPS) aided Inertial Navigation System (INS). Keywords: Vehicle Positioning...

This report describes a combined steering and brake actuator system for use in automatic vehicle control research The system allows a standard passenger car to switch from normal manual operation to automatic operation and back in a seamless manner using largely standard parts. The system uses a...

This report presents two performance enhancement lateral control designs for single unit heavy vehicles. It is shown that robust performance can be achieved using the techniques on a feedback linearized system.

This nal report describes the application of computer vision techniques to the lateral and longitudinal control of an autonomous highway vehicle. In the part of the project we focused on an analysis of the vehicle's lateral dynamics and the design of an appropriate controller for lateral control...
